  1. Data are expressed as mean ± SD. CO, cardiac output; HR, heart rate; IVS, interventricular septum; LV, left ventricle; LVEDD, left ventricular end-diastolic diameter; LVEF, LV ejection fraction; LVEDV, LV end-diastolic volume; LVESD, LV end-systolic diameter; LVESV, LV end-systolic volume; PASP, pulmonary artery systolic pressure; PWT, posterior wall thickness; RV, right ventricle; RVEDD, right ventricular end-diastolic diameter; RVEF, RV ejection fraction; RV FAC, fractional area change; SV, stroke volume; TAPSE, tricuspid annular plane systolic excursion; *P < 0.05, third trimester vs. baseline within each imaging modality.
